How EFFEXOR XR Works

The exact mechanism of venlafaxine in treating these conditions is not fully understood, but it is believed to be related to the potentiation of neurotransmitters in the central nervous system. The drug works by inhibiting the reuptake of serotonin and norepinephrine. By blocking this reabsorption, the medication increases the activity of these chemicals to produce its therapeutic effects.
